Time Length
  • 3 Days
Instructions
  • Make a new wiki titled 14-2 Stoichiometry pt 1.
  • For 4 total problems (choose randomly 1 from each section so I know you didnt copy) show your work by showing how to set up the problem and giving the answer.)
    • Put these 4 problems at the top of your page
    • Example how many grams do 15 moles of Hydrogen weigh?
      1. (put the 4 parts here) 15 mol H/1 mol H = X g H/1.008 g H
      2. (put the answer here ) X = 15.12 g H
  • Round all answers to 2 decimal places.
  • For all the rest of them, just give the full answer after doing the work on scrap paper.
